Scare Them Boo!

"Scare Them Boo!" is a song from the Fraggle Rock episode, "Scared Silly". Philo and Gunge sing to Wembley about the proper way to scare someone. Wembley takes a verse to himself back in the rock, where some creatures spook him and sing as well. Wembley scares them all away with a simple "Boo!"
